etiolate

[ee-tee-uh-leyt]

verb

to cause (a plant) to whiten or grow pale by excluding light

Explanation

To etiolate means "to cause to whiten or grow pale by excluding light," usually when you're talking about a plant. It sprouted from an Old French term meaning "straw" — in other words, pale, dried-out stems and stalks. So open your curtains and let in some sun before you etiolate your plants!

blithesome

[blahyth-suhm]

adjective

lighthearted; merry; cheerful

Explanation

If you're feeling blithesome, you're cheerful, merry, and lighthearted. The term comes from an older word "blithe," which curiously has the same bright meaning. You might feel blithesome on sunny days, after a strong cup of morning coffee, or when you hear good news. Why not share a little blithesome spirit today?

remora

[rem-er-uh]

noun

an obstacle, hindrance, or obstruction

Explanation

A remora is an obstacle, hindrance, or obstruction that slows you down or gets in your way. The word originally referred to a fish known for clinging to sea animals and slowing them down. Whether it's traffic, tech glitches, or plain old bad timing, we all hit a remora now and then.

primogeniture

[prahy-muh-jen-i-cher]

noun

the state or fact of being the firstborn of children of the same parents

Explanation

Primogeniture refers to the state of being the firstborn of children of the same parents. The term is built from Latin roots meaning "first" and "birth." It might sound like old-school law, but if you've ever joked about your eldest sibling getting all the perks, you're talking about primogeniture.

arenaceous

[ar-uh-ney-shuhs]

adjective

sandlike; sandy

Explanation

If something is arenaceous, it has the texture or quality of sand. This word comes from Latin and shares a root with "arena," once a sandy battleground for gladiators. Whether you're digging your toes in at the beach or feeling sandy soil in a garden, arenaceous describes all things gritty and granular.
